calyx

(kā`lĭks): see sepalsepal,
a modified leaf, part of the outermost of the four groups of flower parts. The sepals of a flower are collectively called the calyx and act as a protective covering of the inner flower parts in the bud. Sepals are usually green, but in some flowers (e.g.

Calyx

 

the aggregate of usually green outer leaflets, or sepals, surrounding the corolla in flowers having a double perianth. The sepals are separate or fused.

The biological purpose of the calyx is to protect the flower’s internal organs and the developing fruit and to ensure supplementary feeding. In a few plants (Hydrangea, Erica, and some Ranunculaceae) the calyx is large and brightly colored and serves, instead of a corolla (which is either absent or underdeveloped), to attract insects. In some plants (Papaver) the calyx falls off when the flower opens; in others (Ranunculus) it falls off after the completion of flowering. In the majority of plants, however, the calyx remains after flowering and may even proliferate and participate in fruit formation. In Umbelliferae, Compositae, and some other plants the calyx is completely reduced or converted into hairs.

Residual stones are often distributed in parallel renal calyces, so soft lenses that are planted along the percutaneous renal access may increase stone clearance rate, but this technique requires a long learning curve and has significantly longer surgical time and increased risk of soft lens damage.15 In this case, auxiliary channels need to be established to handle the stone fragments outside the field of view of nephroscope.16 Akman et al.7 reported that the establishment of multi-channel increased the stone clearance rate, but significantly extended the surgical time and augmented the bleeding risk.
Thus the gravity related factors are important factors in predieting the success rate of SWL not only for patients with lower calyce stone as it reported in literature but also for patients with stones located in renal pelvis.
Similar to the investigations which help in the access of calyces, other preparations for PCNL patients include, urine culture and sensi-tivity, any urinary tract infection found is treated with oral antibiotics as per culture sensitivity.
The roselle accessions were Bissap with dark red calyces and leaves, Local with light green calyces and leaves, and Samadah with greenish red leaves and light red calyces [15].
The nonneoplastic renal parenchyma shows only glomerular congestion and focal dilatation of the renal calyces. Hale colloidal iron histochemical staining was negative in the tumor cells.
Dysfunction of the sphincters surrounding the calyces, which facilitate synchronized filling and emptying [3], has been proposed as one possible cause.
Also, bear's paw sign was observed due to dilation of the renal calyces on CT of the abdomen (Figure 2).
Radiographically, XGP presents with the "Bear's paw sign," that is, loss of typical kidney contour combined with dilated calyces and contracted pelvis [15].
Subsequent contrast CT urogram showed contrast outlining multiple radiolucent structures within the calyces and pelvicaliceal system, likely representing matrix stones.
